MACHINE FOR CRIMPING BOOTS.

Specification of.Lette1s Patent No. 31,664, dated March 12, 1861.

To all whom it may concern:

Be it known that I, LEvi IV. HAYDEN, of IVilkes-Barre, in the county ofLuzerne and State of Pennsylvania, have invented certain new and usefulImprovements in Boot- Crimping Machines; and I do hereby declare thatthe following is a full, clear, and exact description of the same,reference being had to the accompanying drawings and to the letters ofreference marked thereon.

The naturel of my invention consists in constructing and arranging theseveral parts of this machine in the manner hereinafter set forth.

In the annexed drawings Figures 1 and 3 represent side elevations. Fig.2 is a view of a part which will be described.

In the figures A represents the stand or body of the machine. Upon andto this stand are secured and hinged two bars or arms D, D, the upperends of said bars being formed to correspond with the shape of the torniof the crimp, the insides of said ends being made flat soas to titsnugly against the form F. The lower ends of the bai-s D D are hinged asshown at az, to the stand or frame.

Gr represents a rack bar which is so constructed upon its top F as toreceive the form F. The top 'is provided with a groove in which the formrests. A variety of forms may be used upon the top F, any size beingused at the will of the operator. L represents a pinion which gears intothe rack upon the lower portion of the bar G, and which serves tooperate said bar. The pinion L is secured upon a shaft which lies acrossthe stand A. Upon the shaft of this pinion is secured a ratchet wheel H.I represents a lever connected loosely to the shaft just spoken of andwhich has attached to it a pawl J, which catches into the teeth upon theratchet wheel H, as. seen in Fig. 1. The lever I and pawl J serve tomove the ratchet wheel H in one direction while the ratchet or pawl c,secured to the frame or stand A,

nected to a treadle e, by means of the straps d, d. These clamps consistof two aws pivoted together and regulated by means of set screws la.,7L. Then the leather to be crimped is placed upon the form F the clampsa, a, catch it upon each side, and draw, and secure it down to the form.

P represents a plate with ratchet teeth which teeth serve to catch thetreadle and hold it down when desirable.

E represents a clamp consisting of a bar with two arms which embrace thebars D, D, being pivoted to one of said bars at 2'..

N represents a set screw which passes into t-he end of the bar E andpresses against a chuck R which intervenes between it and the bar D.IVhen the screw N presses against the chuck R it draws the two bars D,D, together and causes them to press at their upper ends against theleather upon the form. Then the screw N is loosened the chuck R may beraised and then the two arms or bars D, D, may be opened.

In using this machine the leather to be crimped is placed upon the formF. The clamps a, a, then take hold upon it on each side. and draw itdown tight upon t-he form by the use of the treadle. The treadle is thensecured down by the teeth on plate P. The bars D, D, are then brought upagainst the leather upon each side of the form and are pressed againstit by means of the screw N. The leather is allowed to remain in thisposition as long as desirable. A tack or two may then secure it to theform and it may be removed to make room for another.

Having thus fully described my invention what I claim as new and desireto secure by Letters Patent is* The employment of the rack bar G and thebars D, D, as constructed, the clamps a, a, the straps CZ, (Z, thetreadle e, clamp E, chuck R and set screw N, arranged and connected toform a machine for crimping leather substantially as specified.
